Overflow detection system for a grease trap

A receptacle comprising:

• a fluid;
• and
• an overflow sensor that includes:
• a switch comprising:
• a float configured to float in the fluid in the receptacle, wherein the float has a first contact;
• a surface that is separate from the float, wherein the surface has a second contact;
• a resilient member coupled between the float and the surfacer, wherein a first portion of the resilient member is affixed to the float and a second portion of the resilient member is affixed to the surface;
• and
• a contact sensor configured to detect a contact between the first contact of the float and the second contact of the surface and responsively generate a signal;
• a processor coupled to the switch;
• and
• a memory including instructions that are executable by the processor for causing the processor to:
• receive the signal from the switch;
• and
• in response to receiving the signal, transmit a notification to a user device that is remote from the receptacle;
• wherein the overflow sensor is configured to generate the signal only when the first contact contacts the second contact.

A method comprising:

• detecting, by a contact sensor of an overflow sensor positioned in a fluid in a receptacle, that a first contact of a surface of the overflow sensor has contacted a second contact of a float of the overflow sensor, wherein a resilient member is coupled between the float and the surface of the overflow sensor, and wherein a first portion of the resilient member is affixed to the float and a second portion of the resilient member is affixed to the surface;
• generating, by the contact sensor, a signal in response to detecting that the first contact of the surface has contacted the second contact of the float, wherein the overflow sensor is configured to generate the signal only when the first contact contacts the second contact;
• receiving, by a processor of the overflow sensor, the signal from the contact sensor;
• and
• based on receiving the signal, transmitting, by the processor of the overflow sensor, a notification to a user device that is remote from the receptacle.
